It's time to make this a bit more difficult. This time, you are only allowed to pot the RED balls, not the yellow ones. But that shouldn't be a problem, surely...
You will have 80s to pot as many RED balls as possible. If you pot all the red balls then you can then pot the BLACK ball.
For every red ball potted, you will get 100 points and potting the black ball gives 200 points.
Any time left over will give you additional points; every second yields 50 points.
